Answer:

(a) Arts take longer

(b) By 2/9 hours

Step-by-step explanation:

Given

Arts = four over nine hours

Maths = two over nine hours

Solving (a): Which takes longer?

First, represent both as fraction

$Arts = \frac{4}{9}\ hours$

$Maths = \frac{2}{9}\ hours$

Convert fraction to decimal

$Arts = \frac{4}{9}\ hours$

$Arts = 0.444\ hours$

$Maths = \frac{2}{9}\ hours$

$Maths = 0.222\ hours$

By comparison:

$0.444 > 0.222$

Hence, Arts take longer

Solving (b): How much longer?

To do this, we calculate the difference.

$Difference = Arts - Maths$

$Difference = \frac{4}{9} - \frac{2}{9}$

Take L.C.M

$Difference = \frac{4 - 2}{9}$

$Difference = \frac{2}{9}\ hours$

Find x.______________a0

velikii [3]

Answer:

$x=4$

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

$\frac{2}{y}=\frac{y}{6}$

$y^2=12$

$y=\sqrt{12}$

$y=2\sqrt{3}$

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

$a^2+b^2=c^2$

$2^2+(2\sqrt{3})^2=c^2$

$4+12=c^2$

$c^2=16$

$c=4$

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

$x=4$
